Abstract

RESUMO: Neste trabalho realizou-se uma caracterização morfoanatômica comparativa, entre as folhas de Nicandra physalodes (L.) Gaertn. e Physalis angulata L. (Solanaceae), espécies de uso na medicina popular, cujas folhas e raízes são indicadas como diurético e antitérmico. As identifi cações botânicas e as morfodiagnoses macroscópicas foram realizadas após estudos morfológicos. Para as morfodiagnoses microscópicas realizaram-se cortes paradérmicos e transversais das folhas (lâmina e pecíolo), clarifi cados e posteriormente corados com safranina e safrablue. Além dos caracteres morfológicos da fl or e do fruto, as duas espécies diferem pelos seguintes caracteres: vascularização da nervura principal em forma de arco em N. physalodes, e semicircular em P. angulata; drusas no mesofi lo de P. angulata; tricomas glandular-estipitados com a glândula apical bisseriada em N. physalodes. As duas espécies distinguem-se principalmente pela morfologia da fl or e fruto e pela anatomia do mesofi lo e vascularização da nervura principal. ABSTRACT: "Comparative pharmacobotanical study on Nicandra physalodes and Physalis angulata (Solanaceae)". In this work a morphoanatomical comparative characterization was carried out between the leaves of Nicandra physalodes (L.) Gaertn. and Physalis angulata L. (Solanaceae) species used in folk medicine, whose leaves are indicated as diuretic and febrifuge. The botanical identifi cation and macroscopical morphodiagnosis were made after morphological studies. The microscopical morphodiagnosis were carried out by paradermic and transversal cuts of the leaves (blade and petiole), clarifi ed and coloured with safranin and astrablue. Moreover the morphological characters of the fl ower and fruit, of the two species can be distinguished by the following characters: N. physalodes has the bundle vascular of the middle vein in arc format; P. angulata has the vascular bundle of the middle vein in a semicircle format; druses in the mesophyll of P. angulata; and the presence of trichomes glandular-estipitate with bisseriate head in N. physalodes. The morphology of fl ower and fruit and the anatomy of mesophyll, the vascular bundles of middle vein are the principal distinctive characters between them.
